Abstract (en)
Provided is an electrostatic transducer that enables improvement of detection accuracy or driving precision while allowing flexibility. This electrostatic transducer (1) is provided with: an insulator sheet (11); at least one electrode sheet (12) which is laminated on the insulator sheet (11), constitutes a region to be used as a detection region or a driving region, is formed of an elastomer comprising a conductive filler, and is provided with at least one terminal part (12b); and at least one bypass conductor (13) which has an electrical resistivity less than that of the electrode sheet (12), is disposed in contact with the electrode sheet (12) so as to lie along a part of the surface of the electrode sheet (12), and is electrically connected to the electrode sheet (12) in the area of contact with the electrode sheet (12) .
